Balance Transfers: How Much Can You Really Save on Credit Card Debt?

A balance transfer can save you hundreds or even thousands of dollars in interest.

How much depends on your balance, your interest rate, the transfer fee, the length of the 0% period and what you can pay each month.

First, what are you paying now?

Credit card accounts that are charged interest carry an average APR of roughly 22%, based on the Federal Reserve's G.19 data.

That's the rate we'll use in the example below.

Say you move $6,600 to a card with a 15-month 0% intro APR and a 5% transfer fee.

The fee adds $330, so your new balance is $6,930.

Fees on these transfers typically run 3% to 5% of the amount moved and get added to the balance on the new card.

If you kept that same $462 payment on the old 22% card, you'd need about 17 months and pay roughly $1,100 in interest.

That puts your savings at around $790.

After 15 months at 0%, you'd still owe about $4,455.

From there, 22% interest kicks in on what's left.

Even without clearing the balance, you'd come out roughly $3,300 ahead.

These figures come from the standard loan amortization formula, assuming a fixed payment and no new purchases.

You apply for a balance transfer card, and once approved, you request the transfer from your old card.

Any balance left after the intro period ends typically starts accruing interest at the card's standard APR.

Many offers require you to transfer within a set window, such as 60 days.

Transfers can take up to 21 days to complete.

Keep paying your old card until you've confirmed the transfer went through.

Intro period length: Offers can run anywhere from three to 21 months.
Transfer fee: Typically 3% to 5%, so factor it into your monthly payment.
Credit limit: Your total transfer, including fees, generally can't exceed the new card's limit.
Your credit score: Growth in balance transfers has come almost entirely from borrowers with scores of 660 or above.

It's worth it when your interest savings beat the fee and you can make real progress during the 0% period.

It may not be worth it if the fee eats most of your savings.

It may also fall short if your credit limit is too low to move much debt.

Another red flag is a budget that leaves little room to pay down the balance.

Who qualifies?

Cards with the best 0% offers generally favor borrowers with good credit.

What does it cost?

Mostly the transfer fee, typically 3% to 5%.

What's a good intro period?

One long enough to pay off as much as possible at a payment you can afford.

Before you apply, read the offer's terms. Issuers must disclose how long the intro rate lasts and which APR applies afterward
